Choose from 20+ distinct superpowers! Lead your team of superheroes to the moon and beyond, and stop the supervillains of PSION—unless, of course, you join them. Posthuman: Guardians vs PSION is an interactive superhero novel by Evan J. Peterson, author of Drag Star!, where your choices control the story. It's entirely text-based, 300,000 words and hundreds of choices, without graphics or sound effects, and fueled by the vast, unstoppable power of your imagination.
